SLI hack how many bridges do you need?

post #1 of 9
Thread Starter 
if you are doing the SLI hack in a non-sli motherboard how many bridges do you need to be able to do it with two cards?

I reckon you will need just one for a 2-way SLI setup.

Q: Do I need SLI bridge? Can I use Crossfire bridges? Can I run SLI without bridge?
A:SLI bridge for MIO interface on card helps cards to transfer data between GPU's without need to use computer PCI-Express interface. Bandwidth of this MIO interface is close to PCI-Express x1. SLI Bridge isn't critical for SLI operation for two single-GPU cards but it helps to lower PCI-Express loading. In simple words FPS in games and tests will be better with SLI bridge. For complex SLI systems, like 3-way SLI or Quad SLI presence of SLI-bridges is essential.
Crossfire bridge cannot be used with NVIDIA cards, the have different pitch, contact amount and configuration. You will damage card trying to use ATI Bridges on NVIDIA cards.
SLI bridge is now required for drivers over version 2xx.xx and SLI will not work if you do not have one.

One SLI bridge.. I believe you only really need two bridges if you're doing 3 way SLI.

My GTX460's are running the hacked SLI drivers with one bridge, since it is all the cards can take.

why would you use more than 1 bridge for a 2card sli?

Just one SLI bridge Use driver version 258.xx and earlier, and you can SLI without a bridge (with a potential performance hit).
